DETAILED DESCRIPTION WITH REFERENCE TO THE FIGURES

The present invention relates to a toy building set comprising a toy building element 20 with a rotatable flywheel 10.

FIGS. 1A-C illustrate a toy building element 20 comprising a flywheel 10.

The toy building element 20 is provided with one or more coupling means 24 that enable(s) mounting of the toy building element on at least one other toy building element 40 that comprises complementary coupling means. Thus, the toy building elements are capable of being interconnected to form a structure that is capable of constituting or partaking in a toy building set. In the example shown in FIGS. 1A-C, the toy building element 20 has several coupling means 24, 30. At least the one of the toy building elements in the toy building set comprise(s) several coupling means to ensure that the toy building elements can be interconnected in several ways. In the example shown in FIG. 1A, the toy building element 20 comprises coupling means 24 in the form of four studs formed on a building-element coupling part 22 and on the upper face 22′ thereof. On the lower face 22″ of the building-element coupling part 22, other coupling means (not shown) may be provided, eg recesses for receiving studs 30, like on the upper face 22′.

According to one embodiment, a toy building element 20, 40 may comprise at least two different types of coupling means 24, eg coupling studs 30 and complementary coupling means, respectively, for receiving the coupling studs in the form knob-receiving recesses 31 as shown in FIG. 15. According to one embodiment, the coupling part 22 of the building element has coupling studs 30 configured on an upper face 22′ and knob-receiving recesses 31 configured in the lower face 22″. According to other embodiments (not shown), either coupling studs 30 or knob-receiving recesses 31 can be configured on/in one or both faces 22′, 22″. In other embodiments, other types of complementary coupling means 24 can be used, see below.

Thus, it is an option that the toy building element 20 comprising a flywheel can be mounted on another toy building element 40 in many different positions in order to thereby achieve different possible combinations and hence increased play options. This is shown in FIGS. 1A-C, the second toy building element 40, shown next to the toy building element 20 in uncoupled state in FIG. 1A, being coupled to the toy building element 20 in one manner in FIG. 1B, and in another manner in FIG. 1C. In the shown example, the second toy building element 40 is a simple box or a box-shaped structure with coupling means 24 in the form of studs 30 on one side and with coupling means in the form of knob-receiving recesses (not shown) on the opposite side. In other embodiments, the second toy building element 40 may be shaped in other ways. One example is shown in FIG. 14.

The toy building element 20 of FIGS. 1A-C may be coupled to the studs 30 on the toy building element 40 in that the coupling part 22 of the building element is configured with knob-receiving recesses 31 shown in FIG. 15.

The toy building element 20 comprises a flywheel 10. The flywheel comprises at least one actuator mechanism 21. In the example illustrated in FIG. 1, two actuator mechanisms 21 are provided. The actuator mechanisms 21 are configured as two toothed wheels 21′ that are positioned with a toothed wheel to each side of the flywheel 10. The actuator mechanisms 21 are actuated by means of an actuator means which is depicted in FIG. 1 in the form of a rack 1. In other embodiments (not shown), a toothed wheel 21′ may be arranged only to the one side of the flywheel 10.

The rack 1 comprises a grip/handle 3 and an elongate structure extending from the handle 3. The rack 1 comprises teeth 5 that are formed on the elongate structure and are capable of meshing with the teeth on a toothed wheel 21′. When the handle 3 is pulled, the movement of the rack 1 will actuate and hence rotate the toothed wheel 21′ which transmits the rotary movement to the flywheel 10.

The toy building element 20 comprises a connecting structure 23 and a building-element coupling part 22. The connecting structure 23 connects the flywheel 10 and the building-element coupling part 22 to the effect that it is possible to couple the building element 20 having the flywheel 10 to other building elements with complementary coupling means, eg as shown in FIGS. 1B and 1C.

The connecting structure 23 extends from a position on the axis of rotation 25 of the flywheel past the periphery of the flywheel to the building-element coupling part 22. In the embodiments shown in FIGS. 1A-C, 2-4, 9, 11-13, and 16-17, the connecting structure forms a frame 80 that extends around the flywheel 10 in a plane that traverses the axis of rotation 25 of the flywheel. In the embodiments shown in FIGS. 5-8 and 15, the connecting structure 23 extends only in one direction from the axis of rotation 25 of the flywheel. In the embodiment of FIG. 15, the connecting structure 23 and the building-element coupling part 22 thus form a U-shaped construction around the periphery of the flywheel. In the embodiment shown in FIGS. 1A-C and 2-4, and in the embodiment shown in FIG. 9, the frame on the one side of the axis of rotation of the flywheel is merely a simple brace 23′.

The building-element coupling part 22 comprises at least one face 22′, which face comprises one or more coupling means 24.

The building-element coupling part 22 may, as shown in the embodiments of FIGS. 1-4, 9, and 15, also comprise coupling means 24 in the form of a through-going hole 32 through the building-element coupling part 22. Cooperating coupling means (not shown) may be formed on the second toy building element 40, 50. As shown, that through-going hole 32 may be formed in combination with studs 30 and/or stud-receiving recesses 31. In other embodiments (not shown) such through-going hole 32 may be formed on the building-element coupling part 22 without studs 30 and/or stud receiving recesses 31 being also formed. Coupling means 24 in the form of a through-going hole 32 will allow the toy building element 20 having flywheel 10 to be coupled rotatably to the second toy building element 40.

The connecting structure 23 may also comprise one or more coupling means 39. Those coupling means 39 comprise both coupling studs, complementary coupling means for receiving coupling studs, recesses, or the like.

Thus, the connecting structure 23 and/or the building-element coupling part 22, and hence the toy building element 20, could be interconnected with one or more other toy building elements 40, 50 comprising complementary coupling means.

The toy building element 20 with the flywheel 10 comprises actuator mechanisms 21 (as shown in the form of toothed wheel 21′) for meshing with an actuator means (as shown in the form of a rack 1) for causing the flywheel 10 into motion to the effect that the flywheel 10 rotates. The actuator means may be constituted of a rack 1 or the like capable of meshing with a toothed wheel 10.

In the shown embodiments as illustrated in the figures, the building element 20 comprises at least one toothed wheel 21′ being functionally connected to the flywheel 10. The toothed wheel 21′ and the flywheel 10 are structurally connected to the effect that the flywheel 21′ is capable of transmitting a movement to the flywheel 10 whereby the flywheel 10 rotates freely.

FIGS. 1A-C illustrate that the toothed wheel 21′ comprises complementary means (in the form of teeth) relative to the tines 5 of a rack 1. A pull movement in the rack 1 therefore enables translation of the movement into rotary movement from the toothed wheel 21′ to the flywheel 10.

In preferred embodiments, the toy building element 20 is constructed symmetrically to the effect that there is a toothed wheel 21′ to both sides of the flywheel 10. This will appear from FIGS. 2 and 15 that show an embodiment of the toy building element.

The toy building element 20 comprises a building-element coupling part 22, which building-element coupling part 22 comprises an upper face 22′ comprising one or more coupling means 24.

In different embodiments of the toy building element 20, the plane which is defined by that face 22′ may have different orientations relative to the flywheel 20 and the axis of rotation 25 of the flywheel.

FIGS. 1-4 illustrate an embodiment wherein the upper face 22′ of the building-element coupling part 22 extends in extension of the connecting structure 23 away from the axis of rotation 25 of the flywheel, ie the plane coincides with a plane through the axis of rotation 25 of the flywheel and which comprises the axis of rotation 25 of the flywheel.

FIGS. 5-8 illustrate an embodiment wherein the face 22′ of the building-element coupling part extends in a direction which is in parallel with a tangent to the periphery of the flywheel and comparatively perpendicular to the connecting structure.

The planes that are constituted by the faces 22′ of the building-element coupling part in the two embodiments illustrated in FIGS. 1-4 and 5-8, respectively, are thus at right angles to each other.

However, it will be possible to have a construction for the toy building element where the plane of the expanse of the face 22′ of the building-element coupling part is oriented differently than was shown in the two shown examples.

The connecting structure 23 of both embodiments, as shown in the figures, comprises positioning means or guides 26 in the form of a passage transversely through the connecting structure 23 in order to guide the actual meshing of the teeth 5 of the rack 1 with the teeth of the toothed wheel 21′. That guide 26 may be formed by a hole guiding the rack 1 to the effect that the rack 1 will be substantially perpendicular to the connecting structure 23 and/or the face 22′ of the building-element coupling part when they engage, as it is illustrated in FIGS. 1-4 and 15.

However, the guide or positioning means 26 may also be a canal with tapering sides as illustrated in FIG. 8. Here the rack 1 forms an angle relative to the connecting structure 23 and/or the face 22′ of the building-element coupling part when they engage, as illustrated in FIG. 8 where the angle is different from a right angle.

In the embodiments of the toy building element 20 shown in FIGS. 9, 11-13, and 16-17, a guide 26 for a rack 1 is formed, wherein the guide 26 is configured for allowing the rack 1 to be inserted through the frame 80 of the connecting element 23 longitudinally along the plane of the connecting element that extends through the axis of rotation of the flywheel 10 and comprises that axis. Thereby, in those embodiments, the rack 1 is conveyed at right angles to the direction in which it is conveyed in the embodiments shown in FIGS. 1-4, 9, and 15.

The flywheel 10 can be activated via activation of one or more activation mechanisms 21. FIG. 1 illustrates an embodiment wherein two toothed wheels 21′ are provided, one toothed wheel 21′ to each side of the flywheel.

FIG. 5 illustrates an embodiment in which one toothed wheel 21′ is provided. In that embodiment, the toothed wheel 21′ is connected in a rotation-resistant manner to flywheel 10 whereby the rotation force 21′ of the toothed wheel is transmitted directly to the flywheel 10.

Thus, the flywheel 10 can be connected in a rotation-resistant manner to the toothed wheel 21′—either directly to the effect that the toothed wheel is a part of the flywheel, or via an axis of rotation 27.

It is possible to construct a rotatable flywheel 10 which is actuated by a rack 1 in other ways than the embodiments illustrated.

Therefore, the embodiments are to be perceived merely as two alternative options and are not to be construed as limiting as to how the connection between flywheel and the actuating rack can be constructed.

The connecting structure 23 may be securely connected to a position on the axis of rotation 25 of the flywheel, as shown in FIG. 2, or the connecting structure 23 may comprise one or more shaft coupling means 29 for coupling to the shaft 27 of the flywheel as illustrated in FIGS. 6 and 7, which shaft coupling means 29 comprise a bearing 29′ for rotatable attachment of the shaft of the flywheel.

The flywheel 10 is illustrated with a circular periphery, but the flywheel 10 may, in combination with the embodiments described above, also be configured with other shapes, eg an oval-shaped or an angled periphery.

FIG. 9 shows an embodiment of a toy building element 20. That toy building element is substantially the same as the toy building element 20 shown in FIGS. 1-4. In FIG. 9 it is shown that the toy building element 20 can be coupled to a shell element 50. In that case, the shell element 50 is coupled to the toy building element 20 by means of mini-building elements 60. The mini-building elements 60 cooperate with coupling means in the form of through-going holes 39 on the connecting element 23 and with coupling means in the form of through-going holes 54 on the shell element 50. In that case, the mini-building elements 60 are formed as substantially cylindrical structures 63 that, essentially centrally on the cylindrical structure 63, have a projecting encircling collar 64. Correspondingly, at both ends, a projecting encircling collar 61 is provided that enables the mini-building element 60 to form a detachable, but firmly locked connection with a through-going hole, such as eg through-going holes 39 on the connecting element 23 and through-going holes 54 on the shell element 50. One or more slots 62 is/are formed in the cylindrical structure 63. The slots 62 have the effect that the cylindrical structure 63 may act resiliently with a view to being capable of travelling through another coupling means in the form of a hole, such as eg through-going holes 39 on the connecting element 23 and through-going holes 54 on the shell element 50.

In alternative embodiments (not shown), a shell part 50 may be coupled to the connecting element 23 by means of complementary coupling means that are formed on shell part 50 and the connecting element 23, eg holes and pins or studs and stud-receiving recesses.

FIG. 10 shows an alternative embodiment of a shell part 50 for coupling to a toy building element 20. In addition to coupling means 54, that shell part 50 also has coupling means in the form of studs 30 and cylindrical coupling parts 38 that can be interconnected with complementary coupling means, eg in the form of U-shaped clamping coupling means (not shown).

In FIGS. 9 and 10, the shell part 50 is shown with a centrally through-going hole. That hole allows a rack 1 to be conveyed into the guide 26 order to enter into engagement with a toothed wheel 21′.

FIG. 11 shows an embodiment of a shell part 50 for interconnection with a toy building element 20 wherein there is no such through-going central hole 51. In that embodiment of the toy building element 20, the rack 1 is caused to travel through a guide 26, where the rack is moved in parallel with the plane which is formed by the surface of the building-element coupling part 22 which is connected to the axis of rotation 25 of the flywheel 10 and which extends substantially through the axis of rotation 25 of the flywheel 10.

In FIG. 11, the shell part 50 is not, as was shown in FIGS. 9 and 10, coupled to coupling means on the connecting part 23, but rather to coupling means 24, 33 on the building-element coupling part 22. In further embodiments (not shown), however, coupling means may be provided on the connecting structure 23, too, as described in the above embodiments.

In FIG. 11, the shell part 50 is coupled to the toy building element 20 by means of a mini-building element 60. The mini-building element 60 cooperates with coupling means 24 in the form of a through-going hole 33 with x-shaped cross-section on the building-element coupling part 22, and with coupling means in the form of through-going holes 54 with x-shaped cross-section on the shell element 50. In that case, the mini-building element 60 is made as a substantially elongate structure 66 with x-shaped cross-section. The mini-building element 60 and the coupling means 33, 54 may preferably be configured to form a close frictional engagement that allows a firm, but releasable interconnection.

The x-shaped, complementary coupling means 66, 54, 33 shown in FIG. 11 can replace or supplement the coupling means described above.

In FIG. 11, a building-element coupling part 22 is provided at both ends of the connecting structure 23, ie to both sides of the flywheel. In both building-element coupling parts 22, coupling means 24 are formed in the form of a through-going hole 33 with x-shaped cross-section. In other embodiments, different types of coupling means may be provided at each their end, or, if several coupling means are provided at each end, different combinations of types of coupling means 24.

FIG. 12 shows a frame 80 and a connecting structure 23 which, in combination with a flywheel 10 and a snap element 80, forms the toy building element 20 as shown in FIG. 1. FIG. 13 shows how the snap-element 85 enables an easy way to assemble a toy building element 20 by the snap element 85 being inserted into recesses 82 in the frame 80 for retaining a shaft 27 of a flywheel.

The snap-element 80 constitutes an x-shaped block 86. Correspondingly the recesses 82, in the frame, have a complementary x-shape. The block 86 has a pivot 89 configured for retaining the shaft 27 against a bearing 29 for the shaft 27 in the frame 80.

Locking protrusions 88 are formed on arms 87 that extend in the same direction as the pivot 89. The locking protrusions are configured for locking with complementary means (not shown) in the recesses 82 in the frame 80.

A recess 82 is formed on the frame 80 to each side of the flywheel 10 as will appear from FIGS. 11 and 12.

In FIG. 13, the snap element 80 is shown in a position where it is not pushed down into the recess 82 in the frame. When the snap element 80 is pushed down into the recess as shown in FIGS. 11 and 2, it is locked firmly.

In FIG. 14, another toy building element 40 is shown. That toy building element is configured for being able to interconnect a further toy building element in the form of a human-like FIG. 90 and the toy building element 20 having flywheel 10. Moreover, the figure illustrates yet another type of complementary coupling means.

The toy building element 40 comprises an upper flange 45 with a protrusion 46 and a lower flange 47 with a back-stop protrusion 48 in the form of a flange formed at right angles on the lower flange 47. Flanges 45, 47 and protrusions 46, 48 are configured for being able to engage with a foot-like element 92 of the leg 91 of the human-like FIG. 90. On the fore edge of the foot 92, a protrusion 94 may be provided which is configured for coming into engagement with the protrusion 46. The hold-back protrusion 48 is configured for seizing around the rear side of the foot 92. Thereby the human-like figure may be retained releasably on the toy building element 40. A corresponding coupling mechanism may conceivably be formed directly between a toy building element 20 having flywheel 10 in combination with any of the above-referenced embodiments.

Besides, the toy building element 40 of FIG. 14 comprises a coupling means 44 in the form of a cylindrical, through-going hole 44. Thereby eg coupling by means of a mini-building element 60 is enabled, as was described in the context of FIG. 9, to a through-going cylindrical hole 24, 34 on a building-element coupling part 22, as shown in FIG. 16.

Such interconnection will allow that the human-like FIG. 90 or another toy building element 40 can be coupled rotatably to the toy building element 20 having flywheel 10. By suitable choice of dimensions and materials, the friction in the coupling can be adjusted to the effect that the two toy building elements retained thereby can be manipulated to different mutual positions by a child at play.

FIG. 17 shows how a turnable connection can be accomplished by means of a mini-building element 60 that is formed by a combination of the mini-building element 60 of FIG. 9 and the mini-building element 60 of FIG. 11. That mini-building element also enables a turnable connection between the toy building elements 20, 40, 90.
